Audio hardware maker Harman (HAR-4.8%) sells off for the second day in a row due to concerns about the impact of Apple's (AAPL) just-announced partnerships with several top automakers to integrate Siri with their in-vehicle electronics. A feature called "Eyes Free" will allow drivers to activate Siri with the press of a button on the steering wheel, and could lead to some car buyers opting for the automakers' audio systems instead of Harman's.
